NOZZLE FOR THE SUPPLY 0F LIQ ID on easnous FUEL To FURNACES.

To. all whom it may concern:

Be itknown that I, OSOAR BENDER, engineer, of 12 Berlinerstrasse, Neu-Babelsberg,

he present invention refers to a .nozzle for supplyt; of liquid or gaseous fuel to furpaces, rmova openings of the nozzle.

le pins being provided in the The invention consists in the said pins beng arranged on a bridge which can move in all directions and lies across the current of liquid or gas, the movement of said bridge being limited by suitably provided means. This arrangement affords the important advantage in the supply of liquid or gaseous fuel, that by the pins being violently vibrated in the nozzle-holes the fuel is finely split up and distributed on passing through t e nozzle. As the bridge carryin the pins, is arranged across the path of the uel entering into the nozzle, 'it is violently and,irregu larly moved to and fro by the force (kinetic This movement of the bridge is quite certain to occur, as the energy) of this substance.

sup ly offuel through the nozzle must necessar y take place under a certainpressure in order to enable the nozzle fulfilhn its pur-- pose at all; and such pressure wil always represent a certain velocity, which will suffice to 'roduce the vibratory movement of the bri e and the pins. Besides the fine distribution of the fuel, the pins, which project with their points into the nozzle holes willkeep these holes perfectly clean, as they will be constantly striking against the walls of these holes, and thus prevent dirt or the like from accumulatin Y thereon.

Another important e'ature of the present invention consists in the movement of the bridge with the thereto attached pins being regu able, so as to allow'of varying by this means the degree of distribution of the fuel.

For this pur ose the stroke of the movable bridge is ma e adf'ustable, so that tne vibration must take p ace within a more or less "limited space. Also the motion of the pins in the nozzle-holes is preferably made adrovided to mit in an ad-ustable manner t e approach of the pin-bri ge to the nozzle-head containing the holes. Y

Specification of- Letters Patent.

) Application filed February 28, 1907. Serial No. 359,944.

In the accompanying, drawing the nozzle is exemplified, Figure 1 being a longitudinal sectionalong the direction of, the supply of g el Fig. 2 a transverse section along H in 1g. 1. 1 is the nozzle-cap, the face of which 'is provided with several holes'2 and which is closed at the back in a suitable manner, say by a lid 3. The latter may at the same tlme serve to receive the connection 4 for the supply of the substance to be conducted through the nozzle.

Inside the nozzle a bridge 5 is Patented Meat 1c, 1908.,

arranged movable in all directions and of a l section somewhat smaller'than the inside section of the nozzle.

Attached" to this bri'd e and extending towards the face of the nozz e having the holes 2 are ins 6, the ar-' rangement of which on the bridge is such that each pli n projects into one of the nozzle-z holes I 2. he minimum distance between the bridge 5 and the inner nozzle face is'fixed by set screws 7 adjustably arranged in the bridge and projecting against said nozzle face.

The backward movement of the bridge 5 from the inner nozzle face is limitedby the lid 3 of the'cap 1., which is screwed into the cap, said bridge or parts 'of it, whenf moving backward bear against the nner rim of said lid. By screwing the lid 3 more. or lessdeep into the cap 1, the degree of the backward movement of the bridge may be diminished orincreased. The nozzle ho e ment, and the resulting movement ofthe a hurling movement. The pins ofthe bridge striking violently against the sides of the holes 2 increase the hurling movement of the bridge, and it may be easily regulated .by screwing the lid 3 of the cap 1 more or less deeply into the ca) 1, and by adjusting the set screws 7 If the cap 1 is sufficiently inclined with its nozzle face downward, the ins 6 when the nozzle is at rest will slide into the holes 2, and as the mouths of these holes are of nearly the same section as the pins, the latter will nearly close the mouths, so that the idle nozzle holes are prevented from becoming clogged with dirt.

Having now particularly described and ascertained the nature of my said invention s '2 are conical,"- and the pins 6 of the bridge 5 are of a cylindricalshape, whereby the bridge 5, together with its pins,'may move to and from the noz-f' zle face and may also have a lateral move;

and in what manner the same is to be performed, I declare that what I claim is:

1. In a nozzle for the supply of liquids or gases to furnaces, a nozzle cap rovided with ole's inits nozzle-face, a liquld or gas inlet said cap to all sides thereof, set screws'ad justably, arranged in said bridge, said screws rojectin against the inner nozzle face and imiting t e minimum distance between said bridge and said nozzle face. 1 1

. 2. :A no'zzle forthe supply of liquidsor gases to flli naces, having ah uidor gas inlet, anozzle cap provided Wl'th ho es in thenozzleface, a plate within said, cap arranged ,between said face: and saidv inlet, pins attached to,:said plate and. projecting, into said holes, said late together with said ins having free p ay withln'hsaid ca to all si es, a lid adjustablscrewedinto t e nozzle cap, and an inward yprojecting onsaidlid fOrlimit thebackwar'd movement of said plate. 13,,A. nozzle forthe :supplyof hquids or gases to furnaces having a ll uid or gas inlet,

said plate together with sai having free play within said cap to. ,all sides, and 'set screwsadju'stably arranged in said late and projecting against the. innennoz'zlece.

Ano'zz' e for the. supply of liquid or gas eous fuel to; furnaces, a nozzle cap provided holesinthe nozzle-face, a liquid or gas inlet .oppositejt'o said; nozzle-face, a loose plate within said'fcap arranged between; said el inlet-and sail nozzle-face, pinsattached to. said plate .andgojectin'g, into said holes,

- eeidi la h g. .g W hinsaid cap to P rmit il-i v b ing hm I W e by the force of the eminent of;fuel,;'sfet screws in said plate r0.- ecti'ng against the inner nozzle-face, an an adjustable sto within said cap adapted to limit and reg ate the backward movement of said plate.

5. A nozzle for the supply of liquid or gaseous fuel to furnaces, a nozzle cap provided with holes in the nozzle-face, a liquid or as inlet opposite to said nozzle face, a bri ge within said cap between said nozzle face and said inlet, pins attached to said bridge and projecting into said holes, said bridge being perfectly oose within said cap, set screws adustably arranged in said'bridge, said screws projecting a ainst the inner nozzle face, and an-adjustab e stop within said cap adapted tolimit and regulate backward movement of said bridge.

6. A nozzle for the supply of liquid or gaseous fuel to furnaces, having a liquid or gas inlet, a nozzle cap rovided with holes in the nozzle face, a per ectly loose bridge within said cap arranged between said nozzle face and said inlet, pins attached to said bridge and rojec'ting into said holes, said bridge toget er with its pins having free play withm said ca to all sides, and sto s attached to said bridge, said stops projecting against the inner'face of the ca 1 7, u

7. In anozzle for the su ply of liquid and gaseous fuel to furnaces, t e combination of a nozzle cap provided with holes in the face thereof, a loose bridge arranged within said cap, attached to said bridge and projecting into said holes, said bri ge with its pinshaving play within said cap, set screws adjustably arranged, in said bridge projectin'g against the inner nozzle face, a "d adjustablyscrewedintc the cap toprovide for the regulating of the resulting hur ing movement of said bridge and pinscaused by the force of the current. I x In testimony whereofI have hereunto set my hand in presence of two subscribing witnesses.
